Abstract
The invention is a new process to produce polyparaphenylene vinylene or polyparathienylene vinylene polymers using a sulfonium-based polyelectric precursor. This precursor is treated directly with acid to obtain the polymers required. These polymers have high molecular weights and are particularly advantageous in the plastics transformation field.
